Reflectance Model for Diffraction
A novel method for simulating wave effects using a new wave BSDF without any change to ray-based renderers. The method allows neighboring patches to interfere, and it supports near-field effects.

An Analytic Model for Full Spectral Sky-Dome Radiance
A fully spectral analytical skylight model that can be used as a drop-in replacement of the Preetham model and that corrects most of its known deficiencies.

Physically Based Simulation of Rainbows
This paper presents the first comprehensive technique for simulating the interaction of light with physically based raindrops. The technique is based on ray tracing extended to account for dispersion, polarization, interference, and diffraction. The model matches Lorenz-Mie theory for spherical particles, but it also enables accurate simulation of nonspherical particles.

K-Clustered Tensor Approximation: A Sparse Multi-Linear Model for Real-Time Rendering
This paper presents a novel sparse multi-linear model that allows accurate approximations of high-dimensional visual data. The model can also easily achieve real-time rendering rates on GPUs with compact storage space.

Sparse Zonal Harmonic Factorization for Efficient SH Rotation
This sparse analytic representation for spherical functions, including those expressed in a spherical harmonic expansion, is amenable to fast and accurate rotation on the GPU. The paper investigates approaches for promoting sparsity in the basis representation and applying the basis to problems in real-time rendering.
